I have a few of these cheap box sets, they mainly contain stuff that are now in public domain in Europe.
The Elvis, BB King and Johnny Cash box sets are great if you want a cheap bundle of early albums. I have never had a problem with sounds like reviewers have said, then again I always believe that you get what you pay for.
No budget label will actually remaster and remix tracks to high quality.

This one was hit and miss but has enough superb tracks. For me to keep the set, especially the Marty Wilde and John Leyton stuff.
The Beatles backing Tony Sheridan has been in circulation for decades and it's awful when I first it in the 80s. I remember when Time Life would throw it in for free if you bought their CD's.
